Abstract
The utility model discloses a kind of brush mount component of the anti-pressure-resistant breakdown of carbon dust, including plastics brush holder, plastic bruss frame is arranged in a metal shell, a carbon brush is respectively equipped with the front and rear sides of plastics brush holder, the surface of arranged on left and right sides is respectively equipped with an inductance, two inductance are centrosymmetric, and the metal terminal of an external power supply is equipped between each inductance and plastics brush holder wall, an insulating trip is equipped between the corresponding metal terminal of each inductance.The utility model avoids the metal terminal of external power supply with metal shell because pressure-resistant punch-through caused by caused carbon dust random distribution in motor operation course.
Description
Technical field
A kind of brush mount component of the pressure-resistant breakdown of anti-carbon dust is the utility model is related to, is mainly used in motor.
Background technology
During motor operation, due to the abrasion of carbon brush, carbon dust can form pressure-resistant hit in motor internal random distribution
Break-through road, there is pressure-resistant punch-through so as to occur between the metal terminal of external power supply and metal shell.
Utility model content
The utility model is in order to solve to occur pressure-resistant punch-through between the metal terminal of current external power supply and metal shell
The problem of, a kind of brush mount component of the pressure-resistant breakdown of anti-carbon dust is provided for this.
The technical solution of the utility model is as follows：
A kind of brush mount component of the pressure-resistant breakdown of anti-carbon dust, including plastics brush holder, plastic bruss frame are arranged in a metal shell,
A carbon brush is respectively equipped with the front and rear sides of plastics brush holder, the surface of arranged on left and right sides is respectively equipped with an inductance, during two inductance are in
The heart is symmetrical, and the metal terminal of an external power supply is equipped between each inductance and plastics brush holder wall, corresponding in each inductance
Metal terminal between be equipped with an insulating trip.
The insulating trip is obliquely installed, and the upper end of insulating trip contacts with plastics brush holder wall, by the metal of external power supply
Terminal is enclosed in the lower section of insulating trip.
One end of two inductance connects with corresponding carbon brush respectively, and the other end connects with corresponding metal terminal respectively.
The beneficial effects of the utility model are：
The utility model has added insulating trip between the metal terminal and inductance of external power supply, prevents motor operation course
In form pressure-resistant breakdown path in the region due to the carbon dust that carbon brush abrasion is formed, avoid the metal terminal of external power supply and gold
Belong to shell because of pressure-resistant punch-through caused by caused carbon dust random distribution in motor operation course.
Brief description of the drawings
The utility model will illustrate by example and with reference to the appended drawing, wherein：
Fig. 1 is schematic diagram of the present utility model；
Partial enlarged drawing in Fig. 2 Fig. 1；
Fig. 3 is the schematic diagram of plastics brush holder.
Embodiment
The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
